How can I fix my iPhone visual voicemail?

Some iPhone users may have noticed their visual voicemail stopped working after installing the 3.0 tethering hack. To check and see if you are not receiving your messages have someone leave you a message, then check voicemail manually.

To check voicemail dial your phone number directly from the iPhone. Press "1" to check messages. If you have voicemails waiting for you but no visual voicemail try this fix.

The iPhone will reboot and your visual voicemail should return to normal. This process resets the .ipcc (carrier settings) file that was altered in the tethering hack. Turns out the tethering hack has a side effect of disabling visual voicemail in this file.

On top of the resetting your network settings, be sure to delete any strange looking AT&T profiles that have been created since Jail breaking your phone. Either under "general" or "phone" settings menu.

visual voicemail is mainly caused by a tethering hack, and it's best to access the voicemail box by calling your own number, or just go to: Settings > General > Reset and hit the Reset Network Settings button.

I am writing to try to help folks. I had the same visual voicemail issues as many users. When I received an iPhone 6, visual voicemail did not work. I was sure it wasn't user error, since everything else worked fine in the transition from my iPhone 4 -- I've also had an iPhone second generation and first generation.

So I called AT&T support. I spent 20 minutes talking to someone who was very nice but I later realized was just there to route calls. He passed me to someone who had technical expertise but not enough. That guy, who also was courteous and patient (to his credit; they train well), made it worse. His suggestion set off voicemail altogether.

I myself figured out how to reset the voicemail.

Anyway, I poked around on various internet forums. This problem is not uncommon.

Here is what happened for me. The guy from tech support actually turned out not to be wrong. He said maybe give it 24 hours. That didn't work. But 48 hours -- that did it. Two days later, visual voicemail just appeared.
